No post about Sachin Karta would do justice to him if it doesn’t explore his classical roots. A disciple of the noted Bengali classical singer, Bhismadev Chattopadhyay, he created several raga based film songs. The most noted among these is this gem, sung by Manna Dey. The original song in Bengali is by Kazi Nazrul Islam. A Bengali rendition by Asha Bhonsle is available here.
